Copper is extracted in large amounts from the Earth''s crust by mining of sulphide ores and also oxide ores. The procedure of copper processing involves mining and transporting. Oxide ores are generally processed through hydrometallurgy- heap leaching, solvent extraction and electrowinning. The sulfide ores are usually processed using the method of pyrometallurgy- froth floatation, thickening ...

Zinc mining, investment and price news from MINING. The latest news on zinc mines and properties, mining companies and zinc prices.
Zinc Mining. The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.
